A relatively straightforward Mercenary map, with the nitrogen swimming concept being the main twist. The human invaders, guides for the water areas, and other stuff that was added in Ultimate Edition spice it up a bit, but overall I think it's a map that suffers from the source material not being especially great in the first place. It's just a few repetitive central rooms with mostly small side areas and the water maze beneath it.

I wonder if I'm the only person that actually looks forward to the water maze? I used to dislike it, but now it might be my favorite part of the map. It is fun to navigate with all those fancy doors, tunnels, animated textures, and light effects. Oh, and the music... It fits perfectly. I have the maze completely memorized, but I still enjoy exploring a bit just to see all the colors and effects, and to hear the music.

The big overhead pipes always stand out to me for some reason, just an instantly recognisable image I guess.I like the heated interactions between the mercs and humans, but (as already mentioned) a lot of the layout still seems rather generic and pointless.

Only actually played RTNP:UE a couple of times, though I plan to play through it again with the HD modifications etc.
